  Both 
  femora 
  are 
  preserved 
  although 
  the 
  right 
  is 
  partly 
  dam- 
  

   aged. 
  This 
  element 
  is 
  longer 
  and 
  sturdier 
  than 
  in 
  Linmocyon 
  

   vents 
  but 
  otherwise 
  has 
  about 
  the 
  same 
  curvature. 
  The 
  greater 
  

   trochanter, 
  though 
  exhibiting 
  an 
  enlarged, 
  rugose 
  surface, 
  does 
  

   not 
  project 
  upward 
  so 
  far 
  as 
  in 
  L. 
  verus. 
  The 
  lesser 
  trochanter 
  

   is 
  a 
  posterointernal 
  knoblike 
  process 
  situated 
  at 
  about 
  the 
  same 
  

   height 
  on 
  the 
  shaft 
  as 
  in 
  L. 
  verus, 
  but 
  the 
  third 
  trochanter 
  is 
  dis- 
  

   tinctly 
  higher 
  or 
  more 
  proximally 
  located 
  on 
  the 
  shaft, 
  only 
  

   slightly 
  lower 
  than 
  the 
  lesser 
  trochanter. 
  The 
  distd 
  extremity 
  is 
  

   relatively 
  flattened 
  on 
  the 
  dorsal 
  surface 
  and 
  the 
  patellar 
  trochlea 
  

   not 
  so 
  long 
  as 
  in 
  L. 
  verus 
  but 
  with 
  the 
  depression 
  carri'sd 
  upward 
  

   on 
  the 
  shaft 
  well 
  beyond 
  the 
  termination 
  of 
  the 
  articulating 
  sur- 
  

   face. 
  

  

  The 
  preserved 
  portion 
  of 
  the 
  tibia 
  is 
  relatively 
  robust, 
  and 
  

   curved, 
  as 
  described 
  for 
  L. 
  verus, 
  but 
  the 
  cnemial 
  crest 
  is 
  promi- 
  

   nent 
  and 
  extends 
  distally 
  a 
  greater 
  distance. 
  The 
  proximal 
  ex- 
  

   tremity 
  is 
  missing 
  but 
  the 
  posterior 
  surface 
  shows 
  a 
  rather 
  deep 
  

   groove 
  between 
  the 
  ridges 
  supporting 
  the 
  condyles, 
  emphasized 
  

   in 
  part 
  by 
  crushing. 
  The 
  distal 
  extremity 
  may 
  not 
  be 
  entire. 
  It 
  

   terminates 
  in 
  a 
  simple, 
  nearly 
  flat 
  surface 
  v/ith 
  a 
  steep 
  dorso- 
  

   lateral 
  slope 
  for 
  articulation 
  with 
  the 
  astragalus. 
  The 
  internal 
  

   mTlIcolus 
  may 
  not 
  extend 
  much 
  below 
  the 
  facet 
  for 
  the 
  astragalus, 
  

  

  t 
  is 
  incomplete.
